Porto Bello stands on the south-eastern side of a fine bay, "in the province of Costa Rica." At the time when Morgan captured it (in June 1668) it was one of the strongest cities in the possession of the King of Spain. It was neglected until 1584, when a royal mandate caused the traders of Nombre de Dios to migrate thither. It then became the port of the galleons,[16] where the treasures of the south were shipped for Spain. The city which Morgan sacked was built upon a strip of level ground planted with fruit-trees, at a little distance from the sea, but within a few yards of the bay. The westward half of the town was very stately, being graced with fine stone churches and the residence of the lieutenant-general. Most of the merchants' dwellings (and of these there may have been 100) were built of cedar wood. Some were of stone, a thing unusual in the Indies, and some were partly stone, with wooden upper storeys. There was a fine stone convent peopled by Sisters of Mercy, and a dirty, ruinous old hospital for "the sick men belonging to the ships of war." On the shore there was a quay, backed by a long stone custom-house. The main street ran along the shore behind this custom-house, with cross-streets leading to the two great squares. The eastward half of the city, through which the road to Panama ran, was called Guinea; for there the slaves and negroes used to live, in huts and cottages of sugar-cane and palm leaves. There, too, was the slave mart, to which the cargoes of the Guinea ships were brought. A little river of clear water divided the two halves of the town. Another little river, bridged in two places, ran between the town and Castle Gloria. The place was strongly fortified. Ships entering the bay had to pass close to the "Iron Castle," built upon the western point. Directly they stood away towards the town they were exposed to the guns of Castle Gloria and Fort Jeronimo--the latter a strong castle built upon a sandbank off the Guinea town. The constant population was not large, though probably 300 white men lived there all the year round, in addition to the Spanish garrison. The native quarter was generally inhabited by several hundred negroes and mulattoes. When the galleons arrived there, and for some weeks before, the town was populous with merchants, who came across from Panama to buy and sell. Tents were pitched in the Grand Plaza, in front of the Governor's house, for the protection of perishable goods, like Jesuits'-bark. Gold and silver bars became as common to the sight as pebbles. Droves of mules came daily in from Panama, and ships arrived daily from all the seaports in the Indies. As soon as the galleons sailed for Spain, the city emptied as rapidly as it had filled. It was too unhealthy a place for white folk, who continued there "no longer than was needful to acquire a fortune." [Footnote 16: With reservations. See p. 13, _note_.]
